1.Introduction
The Taoglas SGGP.18 is a ceramic GPS/GLONASS/GALILEO passive patch antenna
designed for optimal performance on GPS L1 band (1575.42 MHz) and GLONASS L1
band (1602 MHz). With a low-profile thickness of just 4mm and convenient mounting
via standard SMD process, it is ideal for high-volume, low-cost assembly applications.
SGGP.18 is designed for applications in navigation devices, vehicle tracking/fleet
management systems, and telematics devices. It is an excellent choice for applications
in transportation, defense, marine, agriculture, and navigation industries.
This antenna has been tuned for use on a 50mm*50mm ground plane to achieve 2.86
dBi gain at 1575.42 MHz and 3.04 dBi gain at 1602 MHz. In addition to excellent
efficiency, it also offers a broadly hemispherical radiation pattern with stable gain
across elevations.
SGGP.18 is manufactured and tested in an IATF16949 first tier automotive approved
facility. For further optimization to customer-specific device environments, custom
tuned patch antennas can be supplied, subject to NRE and MOQ.
For more information or support with integrating this antenna into your device, please
contact your regional Taoglas sales office.

6. Antenna Recommended Soldering Conditions
6.1. Flux, Solder
• Use rosin-based flux. Don’t use highly acidic flux with halide content exceeding
0.2wt%(chlorine conversion value).
• Use Sn solder.
6.2. Reflow soldering conditions
• Pre-heating should be in such a way that the temperature difference between solder
and product surface is limited to 150℃ max. Cooling into solvent after soldering also
should be in such a way that temperature difference is limited to 100℃ max.
Unwrought pre-heating may cause cracks on the product, resulting in the deterioration
of products quality.
6.3. Reworking with soldering iron
• The following conditions must be strictly followed when using a soldering iron.
